While much attention is paid to the companies and industries Amazon disrupts, the online retailer has also boosted many that are tied to its massive ecosystem.

Amazon is a $545 billion tech titan that keeps on giving. Its stock has gained more than 50% over the past year, and it now trades at $1,146.19 a share.

While some investor portfolios rely heavily on the company, there are ways to diversify without losing out on the company's high-flying performance. According to BMO Capital Markets' Brian Belski, investors can look at other companies tied to Amazon as a way to continue banking on its dominance.

But as Amazon expands its footprint into the retail market, it is starting to develop its own infrastructure and suppliers. The company's massive growth and scale have allowed it to sell items at deep discounts and cut out middlemen.

PayPal

Amazon partners with several credit card and payment processing companies, including PayPal, for its online transactions. While PayPal is able to collect a fee from all of these transactions, the Bernstein analyst Lisa Ellis says their relationship is on the rocks as Amazon moves forward with its own payment offerings.

Applied Optoelectronics

Applied Optoelectronics' largest customer is Amazon. The company derived 47% of its revenue from Amazon in its second quarter but only 10% in its third quarter. The company said it expected Amazon to continue to reduce orders for its components because of Amazon's technology shift from 40G to the faster 100G transceivers.

"We continue to have ongoing discussions with this customer and based on those conversations, we believe the disruption in order flow is related to the ongoing transition from 40G to 100G and not specific to AOI," Stefan Murry, the chief financial officer of Applied Optoelectronics, said on an earnings call.

MasterCard

Amazon partners with several credit card and payment processing companies, including MasterCard, for its online transactions. MasterCard collects fees from all of these transactions. The Bernstein analyst Lisa Ellis, however, sees a strained relationship as Amazon moves forward with its own payment offerings.

Visa

Amazon partners with several credit card and payment processing companies, including Visa, for its online transactions. Visa, like other payment services, makes money off of the fees from all of these transactions. However, the Bernstein analyst Lisa Ellis sees a fickle relationship as Amazon moves forward with its own payment offerings.

Prologis

Prologis' largest tenant is Amazon and, conversely, it is the tech giant's largest landlord. Amazon occupies roughly 16 million square feet of space and pays 3.1% of net effective rent, roughly 50% more than Prologis' next largest tenant, DHL, according to Prologis' financial statements.

International Paper

International Paper supplies roughly half of the cardboard boxes Amazon uses to package and deliver its items. Though IP does not report how much of its revenue goes to Amazon, analysts estimate that it can be 6% to 7% of its total sales, according to a report by Barron's.

Juniper Networks

Juniper Networks provides the network service and support for Amazon Web Services, the cloud unit of Amazon. According to the UBS analyst Steven Milunovich, weak demand from Amazon may have caused Juniper's earnings upset in the third quarter.

"Our industry contacts tell us AWS is changing its data center architecture," Milunovich wrote in a note. "We believe this change could be creating softness in AWS spend on Juniper."
